Security Advisory
CVE-2023-3439
CVE vulnerability detail — eXtreme Datacenter Security Operations
Description
A flaw was found in the MCTP protocol in the Linux kernel. The function mctp_unregister() reclaims the devices relevant resource when a netcard detaches. However, a running routine may be unaware of this and cause the use-after-free of the mdev->addrs object, potentially leading to a denial of service.
